VENDING-MACHINE.

SPECIFICATION forming part f Letters Patent No. 496,281, dated April 25,1893.

Application filed February 20, 1893. Serial No. 463,128. (No model.)

.To a/ZZ whom it may concern:

Be it known that I, HARRY D. PUEsELL, a citizen of the United States,residing at Washington Court-House, in the county of Fayette and Stateof Ohio, have invented certain new and useful Improvements inVending-Machines, of which the following is a specification.

The primary object of my invention is to provide a machine which willdischarge postage stamps upon dropping a nickel in a slot.

The various features of my invention are fully set forth in thedescription of the accompanying drawings making a part of"thisspeciiication, in which- Figurelis an elevation of my improvementinclosed in a case with the front removed. Fig. 2 is a central verticalsection of Fig. l. Fig. 3 is a section on line Fig. 2. Fig. 4 is aperspective view of the package carrier. Fig. 5 is a detail sectionalview, showing the devices for exposing the coin last inserted into themachine.

1 represents the case in which the vending machine is arranged.

2 represents a Wheel or drum mounted upon an axis 3, which revolves injournal boxes 4.

A represents clamping jaws in which the article B to be vended iscarried; a series of these jaws is arranged around the periphery of thedrum 2. The clamping jaws are composed of two sections a, b; the sectiona being preferably rigidly attached to the periphery of the drum, andthe section b hinged thereto by pivots c.

e represents a spring attached between the jaws and so disposed as tonormally hold them closed.

O represents a tripping arm attached to the hinged jaw b.

5 represents a chute projecting up through the top of the case to slot 6into which a coin is dropped for tripping the locking mechanism andmoving the drum one step. Said chute 5 is hinged upon the axis 3; thetop of the case is provided with a slot `or recess 7 so that said chutecan be moved against the pressure of the spring 8.

9 represents the coin which drops upon a stop 10 and engages with one ofthe series of teeth 11 attached to the rear face of drum 2', as shown'in Figs. 2 and 3. Now when the chute 5 is moved against the spring thecoin 9 catches one of the teeth 10 and moves the drum one step, when thecoin being released from pin 10 drops out into the compartment 12.

13 represents a trip beneath the periphery of the drum against which thearms C of the clamping jaws are successively carried. As the arm Cstrikes the trip, the jaws are opened and the package B discharged intothe compartment 14 which is provided with a suitable opening fordischarging it from the case. This movement carries the particulartripping arm past the spring stop 13 which goes back into position forthe tripping of the next set of jaws.

15 represents a chute on to which the coin is dropped to direct it intothe compartment 12.

It is desirable to have an automatic means of indicating when the chargeof packages has been delivered, or when the drum is empty; this Iaccomplish by the following instrumentalities: 16 represents a hingeddoor which is normally held closed by the catch 17. 18

yrepresents a finger attached to the casing and resting upon the face ofthe drum. 19 represents a tripping rod adapted to engage therewith thistripping rod preferably carries the catch 17, so that when the wheelisturned un'- til the tripping lug 20 is brought round opposite the finger18 it will raise said finger and with it the tripping rod 19 anddisengage the spring catch 17 'by lifting it up, when the door 16 willdrop down closingthe slot and thereby showing that the wheel has madeone revolution and discharged all of its packages. 21 represents aspring friction brake engaging with the surface of the drum disk,preventing the drum or wheel from turning except through the force ofthe lever spout 5. 22 represents a guide for discharging the package Bout of the orifice 23. I have not shown in the drawings a door oropening into said case for loading the jaws, but a door may be used, orthe entire front face removed, as desired.

It is desirable to have the vending machine expose the coin lastinserted and then to automatically dump said coin as the next one is putin and the mechanism actuated to deliver a package; to accomplish thisresult I pro- IOO vide the following instrumentalities: f represents aseries ot' pins inserted in the back of the drum 2; these engagesuccessively with the tripping lever g. h represents a connecting rodhinged to the dumping lever i; said lever is provided with the fork 7aengaging over a pin 'a projecting from the pivot shelf m on which thecoin is deposited as shown in Figs. 1 and 5. o represents a retractilespring secured to the bottom of the case and the 1ever t' for bringingit back into position and raising the shelf m up in position to hold thecoin for exposure; an Ordinar glass being of course provided in the caseopposite the shelf m.

The general features of the moving mechanism are substantially the sameas shown in Letters Iatent No. 432,139, granted me July 15, 1890, butwith improvementsin details of construction.

The operation is as follows: The seveial jaws are each supplied say withtwo postage stamps, which are preferably placed in an envelope and theenvelope inserted between the jaws cui); when the drum has been loadedit is brought to a starting position, say the jaw A brought opposite thespring trip 13; when the coin is dropped into the chute 5 it arrives atthe position shown in Figs. 2 and 3; the chute is then moved by hand,swinging in the slot 7 which carries the said jaws A past the trippinglug 13, opening up the jaws and dropping the package into thecompartment 14; and discharging the coin on the shelf m from spout 15,and it is carried into the compartment 12 by the lever z'- which isoperated automatically and successively by the pins f and tripping arm gand connecting parts as before explained; after the coin is dischargedon to chute 15 the chute 5 may be moved freely without moving thevending wheel. A second coin is dropped causing an engagement of thelever through the coin with the teeth 11 and a second movement of thevending wheel will take place. Vhen the wheel has been turned entirelyround so that the last package has been discharged, the tooth 20 willengage with the finger 18, lifting the tripping rod 19 and dropping thedoor 16, thereby indicating that the packages are all delivered,and itis refilled and started as before.

Having described my invention, what I claim is 1. In a vending machine,the combination with the casing of a rotating drum, a series of carrierjaws a, b, adapted to engage and hold the article to be vended, rotatingmechanism brought into engagement by means of the coin chute lever 5 andthe tripping mechanism for opening the jaws successively as said drum issuccessively moved, substantially as described.

2. In a vending machine, the combination ot' the rotating drum having aseries of teeth 11, the lever chute 5, a stop 10, and a series of springholding jaws a, b, arranged around the periphery of the drum, arm C, andthe spring trip 13, substantially as described.

3. In a vending machine, a drum 2 mounted upon an axis provided with aseries of spring clamping jaws a., b, tripping mechanism opening saidjaws at the particular point of rotation, a chute lever 5 and means forbringing a coin dropped into said slot in engagement with the teeth formoving the drum one step, substantially as described.

4. In a vending machine, in combination with the rotating drum 2, aseries of spring jaws a, Z), arranged around the periphery of said drum,and adapted to clasp and hold a package, and means for tripping saidjaws successively as the drum is rotated, substantially as specified.

5. In a coin-vending machine, the combination with a casing, andacoin-chute, of a door 16 adapted to drop down when released for closingthe coin-chute, a trip-rod 19 for holding the door in its open position,and a rotarypackage-carrier-drum having a trip lug 2O to move thetrip-rod and release the door, so that the latter drops downward andcloses the coin chute, substantially as described.

G. In combination with a vending machine containing a rotating drum 2,the series of pins arranged around said drum, a tripping lever g, adumping lever t' hinged to the shelf on, and means for bringing the saidparts back into normal position as the pins successively pass thetripping levert, substantially as described.

In testimony whereof I have hereunto set my hand.

HARRY D. PURSELL.
